The SWIFT sensor can be fully integrated into the simulation process, since it is
an optimal feedback transducer for use with MTS Remote Parameter Control
(RPC) software. The transducer takes data at points where fixturing inputs are
located rather than at traditional instrumentation points along the vehicle’s
suspension. Using the SWIFT sensor saves you instrumentation time, and fewer
iterations are required to achieve good simulation accuracy.
Measuring spindle loads allows engineers to generate generic road profiles.
Generic road profiles are portable across various vehicle models, do not require
new test track load measurements for each vehicle, and eliminate additional
RLDA tasks.
Four of the six loads measured by the transducer directly correlate to the MTS
Model 329 Road Simulator inputs: vertical force, longitudinal force, lateral force,
and braking input.
The same transducers used to collect road data can be mounted directly in the
wheel adapters of the MTS Model 329 Road Simulator. The SWIFT sensor
should then be removed for the durability cycles, to preserve its fatigue life. It
can be replaced by an adapter plate, available from MTS, to duplicate the mass
and center of gravity of the actual SWIFT sensor.
In a typical non-spinning application, a SWIFT sensor is mounted on a road
simulation test fixture, as shown in the following figure.
